[0026] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1-5 As shown, an automatic loading device for a floor-standing boring machine includes an automatic loading machine 1, an interactive positioning device 2 and a machine tool 3. The automatic loading machine 1 can transfer the workpiece to the interactive positioning device 2 and the workpiece is processed by the machine tool 3. The automatic loading machine 1 includes a foot pedal 11, a workpiece turnover area 12, two interactive tooling plate upper and lower mechanisms 13 and a frame 14. The foot pedal 11 is fixed on the ground, the workpiece turnover area 12 is located on the upper end surface of the foot pedal 11, each interactive tooling plate upper and lower mechanism 13 is arranged on the frame 14, the workpiece turnover area 12 is closely connected with the two interactive tooling plate upper and lower mechanisms 13, the interactive positioning device 2 also includes a positioning workbench 21, a machine tool workbench 22, and a second interactive tooling plate 23. The positioning workbench 21 is fixed on the machine tool workbench 22, and the second interactive tooling plate 23 is arranged on the positioning workbench 21. The interactive positioning device 2 is connected with the automatic loading machine 1, and the interactive positioning device 2 is arranged on the machine tool 3. The interactive positioning device 2 also includes a driving member (not shown in the drawings) that can drive the positioning worktable 2 to reciprocate along the length direction of the workpiece turnover area 12. The driving member is a prior art in the field of machine tools and will not be described in detail here.

[0028] In the present application, the automatic loading machine 1 has two interactive tooling plate upper and lower mechanisms 13. Specifically, when in use, the operator places the workpiece to be processed on the workpiece turnover area 12 through the foot pedal, and transfers the workpiece to be processed on the workpiece turnover area 12 to one of the interactive tooling plate upper and lower mechanisms 13 according to the processing needs. In addition, the above transfer process can also be transferred by a fixture.

[0029] In the present application, two interactive tooling plate upper and lower mechanisms 13 are selected, one of which can clamp the workpiece that has been processed on the interactive positioning device 2, and the other interactive tooling plate upper and lower mechanism 13 can place the workpiece to be processed on the interactive positioning device 2 for processing by the machine tool 3. The two interactive tooling plate upper and lower mechanisms 13 cooperate with each other to realize the loading and unloading of workpieces.

[0030] Further, each interactive tooling board upper and lower mechanism 13 includes a double-row U-shaped conveying beam 131, a screw nut transmission mechanism 132, a servo motor 133, a plurality of independent slide rails 134, a plurality of oil cylinders 135, a double-row support bar 136, a hydraulic system 137, and a first interactive tooling board 138. The screw nut transmission mechanism 132 also includes a screw 1321, a nut 1322, a left bearing seat 1323, and a right bearing seat 1324. The plurality of independent slide rails 134 are fixed on the frame 14, and the double-row U-shaped conveying beam 131 is slidably matched with the plurality of independent slide rails 134. The double-row U-shaped conveying beam 131 is fixedly connected with the nut 1322 provided on the screw nut transmission mechanism 132. Then, the nut 1322 cooperates with the screw rod 1321, the left end of the screw rod 1321 cooperates with the left bearing seat 1323, and the right end of the screw rod 1321 cooperates with the right bearing seat 1324. The left bearing seat 1323 and the right bearing seat 1324 are fixed on the frame 14, one end of the screw rod 1321 is connected to the servo motor 133, and the servo motor 133 is fixed to one end of the right bearing seat 1324. A number of cylinders 135 are arranged on the double-row U-shaped conveying beam 131, and double-row support bars 136 are mounted on the output ends of a number of cylinders 135. The hydraulic system 137 is arranged in the middle of the frame 14 and below the interactive tooling board upper and lower mechanism 13, and the first interactive tooling board 138 is positioned on the double-row support bars 136.

[0031] Further, such as Figure 6 As shown, the upper surface of the double-row U-shaped conveying beam 131 is provided with a plurality of cylindrical grooves 1311, each cylindrical groove 1311 is matched with a cylinder 135, the cylinders 135 are equipped with sensors (not shown in the figure), and the hydraulic system 137 supplies oil pressure to the cylinders 135 through a diverter valve (not shown in the figure), so as to realize the synchronization of the cylinders 135. This is the prior art and will not be described in detail here.

[0032] In the present application, when the double-row U-shaped conveying beam 131 delivers the workpiece into place, the hydraulic system 137 supplies oil pressure to the plurality of cylinders 135 through a diverter valve (not shown in the figure) to ensure that the four cylinders are lifted synchronously. When the plurality of cylinders 135 lift the workpiece, the sensors equipped on the plurality of cylinders 135 themselves detect the lifting level to ensure the levelness of the workpiece, thereby ensuring the accurate placement of the processed workpiece.

[0033] Further, such as Figure 7-8As shown, a double row of cylinders 1361 are provided on the upper surface of the double row of support bars 136, and an outer hole 1381 and an inner hole 1382 are provided on the bottom of the first interactive tooling board 138. The double row of cylinders 1361 and the outer hole 1381 are positioned in cooperation to prevent the first interactive tooling board 138 from shifting.

[0034] In the present application, the double-row cylinders 1361 disposed on the upper surface of the double-row support bars 136 are used to position the first interactive tooling plate 138 to ensure the stability of the workpiece during the conveying process.

[0035] Before the workpiece to be processed is shifted from the workpiece turnover area 12 to the first interactive tooling board 138, the first interactive tooling board 138 and the double-row support bar 136 are positioned through the double-row cylinders 1361 and the outer holes 1381, and then the workpiece to be processed is shifted to the first interactive tooling board 138. After receiving the signal from the boring machine, the servo motor 133 drives the screw nut transmission mechanism 132 to slowly extend the first interactive tooling board 138 to the direction of the interactive positioning device 2. At the same time, the boring machine itself moves the interactive positioning device 2 to a position facing the first interactive tooling board 138 under the action of the driving member.

[0036] Further, such as Figure 9-11 As shown, four zero-point locators 211 are arranged around the positioning workbench 21, and the zero-point locator 211 is composed of an annular positioning surface 2111, a clamp 2112, and a small flange 2113. The inner four holes 232 on the second interactive tooling plate 23 cooperate with the clamp 2112 of the zero-point locator 211 for positioning and clamping, and the annular positioning surface 2111 is fitted with the second interactive tooling plate 23 or the first interactive tooling plate 138, and the zero-point locator 211 is fixed to the positioning workbench 21 through the small flange 2113. It should be particularly noted that the zero-point locator 211 is a prior art, and the details can be found in the Chinese patent with the announcement number CN210998590U.

[0037] It should be noted that the first interactive tooling board 138 and the second interactive tooling board 23 are interchangeable structures for realizing alternating cycle continuous processing, and their structures are the same.

[0038] Furthermore, a blowing pipeline (not shown in the figure) is opened inside the zero point locator 211, which is used to clean the annular positioning surface 2111 to ensure that the zero point positioning horizontality is not affected. One end of the blowing pipeline is connected to an external air outlet piece, which can be an existing air compressor or other air supply device, which will not be described in detail here.

[0039] Furthermore, the positioning workbench 21 is smaller than the second interactive tooling board 23, and the outer four holes 231 on the second interactive tooling board 23 are suspended on the outside of the positioning workbench 21, so as to realize the key action of automatic feeding, so as to prevent the double-row support bars 136 on the several oil cylinders 135 from interfering with the positioning workbench 21 when the first interactive tooling board 138 falls or leaves the positioning workbench 21.

[0040] When the boring machine moves the interactive positioning device 2 to the position facing the first interactive tooling plate 138, the plurality of oil cylinders 135 begin to push upwards synchronously and slowly under the action of the hydraulic system 137. At this time, the double-row support bar 136 lifts the workpiece, and then drives the servo motor 133 to make the screw nut transmission mechanism 132 continue to move directly above the positioning workbench 21. After receiving the in-position signal, the screw nut transmission mechanism 132 stops extending, and the hydraulic system 137 makes the plurality of oil cylinders 135 begin to retract slowly and synchronously until the first interactive tooling plate 138 slowly descends onto the positioning workbench 21, and the four zero point locators 211 of the positioning workbench 21 cooperate with the inner holes 1382 on the first interactive tooling plate 138. It should be particularly noted that the inner hole 1382 on the first interactive tooling board 138 and the inner four holes 232 on the second interactive tooling board 23 are equivalent in structure and effect, until the first interactive tooling board 138 is completely positioned on the zero point locator 211, and the zero point detection signal reaches the target value, the servo motor 133 reverses and drives the screw nut transmission mechanism 132 to slowly withdraw, and the clamp 2112 on the zero point locator 211 clamps the inner four holes 232 on the second interactive tooling board 23 or the inner hole 1382 on the first interactive tooling board 138.

[0041] It should be noted that before the first interactive tooling plate 138 is attached to the annular positioning surface 2111 of the zero point locator 211, the annular positioning surface 2111 has been cleaned by blowing, otherwise it will affect the zero point detection signal value. In this way, the automatic feeding is completed.

[0042] On the contrary, after receiving the signal that the boring machine has completed processing, the boring machine itself will also move the interactive positioning device 2 to the position facing the idle double-row U-shaped conveying beam 131 (i.e., another interactive tooling plate upper and lower mechanism 13), and the screw nut transmission mechanism 132 of the idle double-row U-shaped conveying beam 131 station will start to extend. At the same time, the zero point locator 211 on the positioning table 211 will release the first interactive tooling plate 138. After extending it into place, several cylinders 135 will start to push out synchronously. At this time, the double-row support bar 136 cooperates with the inner hole 1382 of the first interactive tooling plate 138 through the double-row cylinder 1361. It should be specially noted that the inner hole 1382 on the first interactive tooling plate 138 and the inner four holes 232 on the second interactive tooling plate 23 have the same structure and effect. After positioning, the processed first interactive tooling board 138 and the workpiece are raised until the first interactive tooling board 138 completely leaves the zero point locator 211. At the same time, after the level of the lifting is detected to be in place, the screw nut transmission mechanism 132 is slowly withdrawn. In this way, the two rows of the upper and lower mechanisms 13 of the two interactive tooling boards are staggered and repeatedly transport and recover the workpieces, completing automatic feeding and unloading.

[0043] In summary, the present invention has the following beneficial effects: through the design and application of the automatic feeding device, the workpieces to be processed are staggered and continuously transported and unloaded, which increases the processing efficiency and greatly reduces the safety hazards of manual operation. The double-row conveying beams, ingenious positioners, positioning structures and sensor applications of the automatic feeding device solve the problems of the flatness of the oil cylinder jacking and the positioning flatness of the positioning workbench, so that the automatic feeding device can replace manual continuous processing and production, greatly improving the processing efficiency.

[0044] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
